A method and droplet dispenser for depositing single particles onto a target. For example, a single particle depositing method with improved rate of dispensing single particles and/or increased recovery of rare particles and/or with an extended applicability with different types of particles and/or operation conditions. The depositing method may be capable of increasing the rate of dispensing single cells without decreasing the recovery rate. Testing a single particle condition is combined with testing a zero particle condition and/or the particle type condition. The ejection and sedimentation regions are tested with regard to the presence of a single particle in the ejection, and further particle arrangements allowing a single particle deposition are identified and tested and/or the particle type detection is added to the dispenser control. Accordingly, the speed and recovery rate of dispensing single particles of interest can be improved.
